Can chitosan be a promising carrier for plant growth-boosting bacteria?

Researchers from Chungbuk National University in South Korea investigated chitosan and its potential as a carrier of bacteria that promote plant growth. The results of their study were published in the journal Archives of Agronomy and Soil Science.

In the study, the researchers immobilized Methylobacterium oryzae CBMB20 – a promising plant growth-promoting bacteria and a biocontrol agent – in different chitosan formulations. They compared wet and dry chitosan with wet and dry alginate in terms of their ability to promote tomato plant growth.
